Approaching from the female connector side trains go straight over it, approaching from the male connector side trains cross over to the opposite track. It's similar to the Y-point included in that opposite direction station where when one train arrives the other leaves, where the trough the wheels ride inside is lowered to cause the crossover but approaching from the other direction leaves it unaffected other then a very small drop.
There is a set with a version of the rail with stickers that explain how it work visually, let me see if I can find it.

I have a website where I have been writing about and photographing many of the sets and pieces that I find interesting.
